Classical compound in the context of Affix

This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine. First, prefixes and suffixes, most of which are derived from ancient Greek or classical Latin, have a droppable vowel, usually -o-. As a general rule, this vowel almost always acts as a joint-stem to connect two consonantal roots (e.g. arthr- + -o- + -logy = arthrology), but generally, the -o- is dropped when connecting to a vowel-stem (e.g. arthr- + -itis = arthritis, instead of arthr-o-itis). Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.

Haloquadratum walsbyi is a species of Archaea in the genus Haloquadratum, known for its square shape and halophilic nature.

First discovered in a brine pool in the Sinai Peninsula of Egypt, H. walsbyi is noted for its flat, square-shaped cells, and its unusual ability to survive in aqueous environments with high concentrations of sodium chloride and magnesium chloride. The species' genus name Haloquadratum translates from Greek and Latin as "salt square". This archaean is also commonly referred to as "Walsby's Square Bacterium" because of its unique square shape. In accordance with its name, H. walsbyi are most abundantly observed in salty environments.

Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure (whether it is acute or chronic), route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices. Toxicology is currently contributing to the field of cancer research, since some toxins can be used as drugs for killing tumor cells. One prime example of this is ribosome-inactivating proteins, tested in the treatment of leukemia.

The word toxicology (/ˌtɒksɪˈkɒlədʒi/) is a neoclassical compound from Neo-Latin, first attested c. 1799, from the combining forms toxico- + -logy, which in turn come from the Ancient Greek words τοξικός toxikos, "poisonous", and λόγος logos, "subject matter").

Translingual phenomena are words and other aspects of language that are relevant in more than one language. Thus "translingual" may mean "existing in multiple languages" or "having the same meaning in many languages"; and sometimes "containing words of multiple languages" or "operating between different languages". Translingualism is the phenomenon of translingually relevant aspects of language; a translingualism is an instance thereof. The word comes from trans-, meaning "across", and lingual, meaning "having to do with languages (tongues)"; thus, it means "across tongues", that is, "across languages". Internationalisms offer many examples of translingual vocabulary. For example, international scientific vocabulary comprises thousands of translingual words and combining forms.

The term also refers to a pedagogical movement and line of research inquiry in composition studies and second-language learning that seek to normalize the simultaneous presence of multiple languages and communicative codes as well as characterize all language use as a matter of mixing and changing these languages and codes. For these teachers and language researchers, the prefix trans in translanguaging "indexes a way of looking at communicative practices as transcending autonomous languages". This prefix provides a different lens of looking at languages and the relationships among them. Rather than considering each language as fixed and closed, a translanguaging perspective considers languages as flexible resources that speakers and writers use to communicate across cultural, linguistic, or contextual boundaries.

Heterogram (classical compound: "different" + "written") is a term used mostly in the philology of Akkadian and Pahlavi texts containing borrowings from Sumerian and Aramaic respectively. It refers to a special type of logogram or ideogram borrowed from another language (in which it may have been either ideographic or phonetic) to represent either a sound or meaning in the matrix language. It is now commonly accepted that they do not represent true borrowings from the embedded language and instead came to represent a separate register of orthographic archaisms.

As an example in English - the written abbreviations e.g., i.e., and viz. are sometimes read respectively as "for example", "that is", and "namely". When read this way, the abbreviations for the Latin phrases exempli gratia, id est, and videlicet are being used logographically to indicate English phrases which are rough translations. Similarly, the ampersand ⟨&⟩, originally a ligature for the Latin word et, in many European languages stands logographically for the local word for "and" regardless of pronunciation. This can be contrasted with the older way of abbreviating et cetera—&c.—where ⟨&⟩ is used to represent et as a full loanword, not a heterogram.
